Answer:
Step-by-step explanation:
(a) To find the momentum of the ball as it leaves the tee, we can use the equation:
Momentum = mass * velocity
Given:
Mass of the ball (m) = 0.145 kg
Velocity of the ball (v) = 15.0 m/s (since it is traveling horizontally)
Momentum = 0.145 kg * 15.0 m/s
Momentum = 2.175 kg·m/s
Therefore, the momentum of the ball as it leaves the tee is 2.175 kg·m/s.
(b) To find the net impulse, we can use the impulse-momentum theorem, which states that:
Impulse = Change in momentum
Since the ball starts from rest (initial momentum is zero) and ends up with a momentum of 2.175 kg·m/s, the change in momentum is:
Change in momentum = Final momentum - Initial momentum
Change in momentum = 2.175 kg·m/s - 0 kg·m/s
Change in momentum = 2.175 kg·m/s
Therefore, the net impulse acting on the ball is 2.175 kg·m/s.
(c) The net force acting on the ball can be found using Newton's second law of motion:
Force = Change in momentum / Time
Given:
Change in momentum = 2.175 kg·m/s (from part (b))
Time (Δt) = 0.0500 s
Force = 2.175 kg·m/s / 0.0500 s
Force = 43.5 N
Therefore, the net force that acted on the ball is 43.5 Newtons.
